GPA calculator
A GPA isn't an average of grades — it's an average weighted by credit hours, which is why that 4-credit chemistry course matters more than a 1-credit seminar. Add one row per course with its credits and final letter grade, and this calculator converts grades to the standard 4.0 scale, sums the quality points, and divides by total credits. Use it at the end of a semester, to project what final grades will do to your cumulative GPA, or to see exactly what raising one grade is worth.

How it works
- 01
Each letter grade is converted to grade points on the standard 4.0 scale (A = 4.0, B+ = 3.3, and so on).
- 02
Quality points are grade points multiplied by credit hours for every course.
- 03
Your GPA is total quality points divided by total credits — weighted exactly the way most registrars calculate it.
